WebRSA is a type of asymmetric encryption, which uses two different but linked keys. In RSA cryptography, both the public and the private keys can encrypt a message. The opposite key from the one used to encrypt a message is used to decrypt it. WebOct 12, 2024 · The Microsoft Enhanced Cryptographic Provider supports direct encryption with RSA public keys and decryption with RSA private keys. The encryption uses PKCS #1 padding. On decryption, this padding is verified. The length of plaintext data that can be encrypted with a call to CryptEncrypt with an RSA key is the length of the key modulus …
